SPECIFICATION forming part of Letters Patent No. 609,422,- dated August `23, 1898.

. Application filed January 18, 1'89'7. Serial No. 619,553. (No model.)

To all whom) it may concern:

Be it known that I, EDWARD FACKNER, of New York, (Brooklym) in the county of Kings and State of New York, have invented a new and Improved Lock, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved lock which is simple and durable in construction,very secure,not liable to get out of order, and easily fastened to the door or other part on which it is to be used.

This invention consists in certain combinations which will be fully described hereinafter and defined in the claims. l

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures.

Figure l is a sectional side elevation of the improvement as applied. Fig. 2 is a sectional plan view of the same. Fig. 3 is a sectional side elevation of part of the improvement and with the tumblers in an inactive position. Fig. 4 is a transverse section of part of the improvement on the line 4. c'of Fig. 2. Fig. 5 is a transverse section of a modified form of the improvement. Fig. 6 is a sectional side elevation of a modified form of cap for the casing, and Fig. 7 is a reduced sectional side elevation of a modiiied form of the improvement.

The improved lock is providedfwith a suitably-constructed casing A, preferably made cylindrical to permit of conveniently fitting the casing into a hole bored in the door B or other part on which the lock is to be used. The outer end of the casing A is formed or provided with a cap A', fastened by bolts, screws, or the like to the door B, as plainly illustrated in the drawings. In the outer end of the casing A is held loosely a bolt in the form of a ball C, projecting with a portion through an opening in the cap A', the opening being less in size than the diameter of the ball, so that the latter is always held within the casing and cannot fallout of the same when the door is opened. The projecting end of the ball C is adapted to pass into a correspondingly-shaped keeper D, secured to the doorcasing B', as indicated in Fig. l. The inner end of the ball C rests in a cup E, pressed' on by a spring F,'entending in the casing A and resting with its rear end on a transverse partition A2, secured to the casing A. y

By the arrangement described the spring F presses the cup E in a forward directiomso as to holdthe ball C normally in an outermost position to engage the keeper D, so as tokeep the door in a closed position. The spring F also permits the cup E and ball C to yield rearwardly, so as to allow'the ball C to pass inward into the casing A at the time the' door is opened, and the projecting end of the ball O passes over the face of the doorcasing B'. Into the bottomof the cup E eX- tends the head G' of the half-round rod G, passing through the wall of the cup and fitted to slide longitudinally in the partition A2 and provided at its end with a plate G2, adapted to be engaged by the free ends of one or more tumblers H H', formed with hubsH2 and H3, respectively, mounted to turn in suitable bearings formed in the brackets I and I', secured in the partition A3, attached to the rear end of the casing A. The adjacent faces of the tumblers H and H' are formed with registering circular grooves H4, engaged by a ring J, mounted in a bracket I2 similar to the brackets I andV I and likewise attached to the partition A3.

Now it will be seen that by the arrangement describedthe tumblers H and H are mounted to swing Vto engage or disengage the plate G2 to lock or unlock the ball C. The latter is always held in an outermost position by the spring F pressing on the cup E, containing the ball; but the ball, with the ycup and rod G, can only move inwardly in the casingwhen both tumblers H H' are out of engagement with the plate G2. `W'hen one or both tumblers engage the plate G2, then the ball is locked in place and when engaging the keeper locks the door. As shown in Fig. 7, the bolt and rod are combined in one piece andthe bolt is in the form of a rectangular block C', with the projecting end C2 half-round to engage a correspondingly-shaped keeper. The rod G3 is formed or secured to the inner end of the block 'C' and is provided with a plate G4.. The cup E' is pressed on by a spring F and engages the block C' to hold the latter normally in an outermost positiomas shown.

From the centers of the tumblers H and H' (see Fig. 2) extend late rally the key-rods K and K', respectively, formed with longitudinal ridges or grooves to permit of using a great variety of key-rods for the different locks, correspondingly-shaped handles and keys being used for the similarly-shaped keyrods. The key-rod K extends centrally in the hub H2, and its free end is adapted to be engaged by a correspondingly-shaped shank L, secured at its outer end to a suitable handle N, adapted to be grasped by the operator to open or close the door, as the case may be, the said handle being arranged on the inside of the door.y The free end of the other keyrod K' extends into the hub H3 and is adapted to be engaged by a correspondingly-shapedkey O, adapted to be passed through a keyplate P, from the outside thereof, so as to open the lock whenever desired. The rear ends of the tumblers H and H' are formed with segmental gear-wheels H5, in mesh with teeth Q', projecting laterally from springs Q, attached to the several brackets I, I', and I2.

Now it will be seen that by the arrangement described the operator by turning the handle N into the position shown in Figs. l and 2 causes the tumbler H to engage the plate G2 and lock the rod G, and consequently hold the ball C locked in an outermost position. As the ball is in engagement with its keeper D, the door is securely locked in place. When it is desired to unlock the door from the inside, the operator turns the handle N, so as to swing the tumbler H upward out of engagement with the plate G2 to allow the rod G to slide rearwardly. Now when a pull is exerted on the door the ball C moves out of the keeper and rolls over the door-casing face, as previously explained. When the door is locked by the tumbler H' and it is desired to open the door from the outside, then the tumbler H must be in an unlocked position, and then the operator by inserting the key O through the key-plate P engages the key-rod K', and then on turning the said key causes an upward swinging of the tumbler H' to disengage the plate G2 and permit the ball O to move inwardly in the casing on a push on the door. 4

It is understood that by the arrangement described the door can be locked from the inside, so that it cannot be opened at all from the outside, the operator simply leaving the tumbler H in its normal position against the plate G2.

lf desired, only one key-rod may be used, as indicated in Fig. 5, the said key-rod, then extending centrally through the tumblers H and H', to be operated on at one end by the handle N and at its other end by the key O.

The cap A' may be made spherical, asindicated in Fig. 6, so as to hold the ball O properl y in place.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent,is-

1. The combination of a casing having a fixed partition therein, a spring-pressed bolt in the casing and arranged at the front side of the partition and comprising a rod movable through the partition, three brackets rigidly held in the casing at the rear side of the partition, two independent tumblers respectively sandwiched between the brackets, and each capable ot' engaging said rod to hold the same, and a key-rod in connection with each tumbler and operative respectively at the opposite sides of the casing.

2. The combination of a casing having a fixed partition intermediate its ends, a bolt arranged in the casing forward of the partition and comprising a rod movable through the partition, three brackets held rigidly in the rear portion of the casing, a ring heldby the central bracket,two tumblers respectively sandwiched between the brackets and each turning on the ring, the tumblers being capable of engaging and holding the said rod, a key-rod attached to each tumbler, the keyrods being operative respectively from opposite sides of the casing, and a spring-pressed tooth respectively engaging the rear portion of each tumbler.

3. The combination of a casing, a bolt arranged in one end of the casing, brackets iixedly held in the casing, a tumbler mounted to turn in the brackets and capable of locking the bolt, the tumbler having a toothed rear portion, a spring carried in the rear of the casing, a tooth carried by the spring and engaging said rear portion of the tumbler,and a key-rod attached to the tumbler and operative from one side of the casing.
